Vulnerability management (VM) has been around for millennia. Cities, tribes, nations, and corporations have all employed its principles. The operational and engineering successes of any organization depend on the ability to identify and remediate a vulnerability that a would-be attacker might seek to exploit. What were once small communities became castles. Cities had fortifications and advanced warning systems. All such measures were the result of a group recognizing their vulnerabilities and addressing them in different ways. Today, we identify vulnerabilities in our software systems, infrastructure, and enterprise strategies. Those vulnerabilities are addressed through various and often creative means. Vulnerability Management demonstrates a proactive approach to the discipline. Illustrated with examples drawn from Park Foreman's more than three decades of multinational experience, the book demonstrates how much easier it is to manage potential weaknesses than to clean up after a violation. Covering the diverse realms that CISOs need to know and the specifics applicable to singular areas of departmental responsibility, he provides both the strategic vision and action steps needed to prevent the exploitation of IT security gaps, especially those that are inherent in a larger organization. Completely updated, the second edition provides a fundamental understanding of technology risks-including a new chapter on cloud vulnerabilities and risk management-from an interloper's perspective. This book is a guide for security practitioners, security or network engineers, security officers, and CIOs seeking understanding of VM and its role in the organization. To serve various audiences, it covers significant areas of VM. Chapters on technology provide executives with a high-level perspective of what is involved. Other chapters on process and strategy, although serving the executive well, provide engineers and security managers with perspective on the role of VM technology and processes in the success of the enterprise.

In 1775, Paul Revere, the folk hero of the American Revolution, galloped wildly on horseback through small towns to warn American colonists that the British were coming. In today's Internet age, how do we warn vast numbers of computers about impending cyber attacks?

Rapid and widespread dissemination of security updates throughout the Internet would be invaluable for many purposes, including sending early-warning signals, distributing new virus signatures, updating certificate revocation lists, dispatching event information for intrusion detection systems, etc. However, notifying a large number of machines securely, quickly, and with high assurance is very challenging. Such a system must compete with the propagation of threats, handle complexities in large-scale environments, address interruption attacks toward dissemination, and also secure itself.

Disseminating Security Updates at Internet Scale describes a new system, "Revere," that addresses these problems. "Revere" builds large-scale, self-organizing and resilient overlay networks on top of the Internet to push security updates from dissemination centers to individual nodes. "Revere" also sets up repository servers for individual nodes to pull missed security updates. This book further discusses how to protect this push-and-pull dissemination procedure and how to secure "Revere" overlay networks, considering possible attacks and countermeasures. Disseminating Security Updates at Internet Scale presents experimental measurements of a prototype implementation of "Revere" gathered using a large-scale oriented approach. These measurements suggest that "Revere" can deliver security updates at the required scale, speed and resiliency for a reasonable cost.

Disseminating Security Updates at Internet Scale is designed to meet the needs of researchers and practitioners in industry and graduate students in computer science. This book will also be helpful to those trying to design peer systems at large scale when security is a concern, since many of the issues faced by these designs are also faced by "Revere." The "Revere" solutions may not always be appropriate for other peer systems with very different goals, but the analysis of the problems and possible solutions discussed here will be helpful in designing a customized approach for such systems.

Today, the Internet has become a source of information that no country or company can forgo. It is not only used to communicate or entertain, but most importantly to operate utilities and public services such as banking or air traffic. As the reliance on computer networks across societies and economies keeps growing, so do security risks in cyberspace - referred to as "cybersecurity." Cybersecurity means protecting information and control systems from those who seek to compromise them. It also involves actors, both malicious or protective, policies and their societal consequences. This collection of essays provides a better understanding of the risks, perceptions, and myths that surround cybersecurity by looking at it from three different levels of analysis: the sovereign state, the infrastructure and stakeholders of the Internet, and the individual. The essays explore such issues as information ownership, censorship, cyberwars, cyberterrorism, privacy, and rebellion, bringing together expert knowledge from computer science and the social sciences with case studies. It reviews existing policies and practices and discusses the threats and benefits of living in an increasingly networked world. This authoritative analysis of one of the most controversial and compelling security debates of the twenty-first century will appeal to scholars and practitioners interested in security, international relations and policymaking.

A hack is any means of subverting a system's rules in unintended ways. The tax code isn't computer code, but a series of complex formulas. It has vulnerabilities; we call them "loopholes." We call exploits "tax avoidance strategies." And there is an entire industry of "black hat" hackers intent on finding exploitable loopholes in the tax code. We call them accountants and tax attorneys. In A Hacker's Mind, Bruce Schneier takes hacking out of the world of computing and uses it to analyse the systems that underpin our society: from tax laws to financial markets to politics. He reveals an array of powerful actors whose hacks bend our economic, political and legal systems to their advantage, at the expense of everyone else. Once you learn how to notice hacks, you'll start seeing them everywhere-and you'll never look at the world the same way again. Almost all systems have loopholes, and this is by design. Because if you can take advantage of them, the rules no longer apply to you. Unchecked, these hacks threaten to upend our financial markets, weaken our democracy and even affect the way we think. And when artificial intelligence starts thinking like a hacker-at inhuman speed and scale-the results could be catastrophic. But for those who would don the "white hat," we can understand the hacking mindset and rebuild our economic, political and legal systems to counter those who would exploit our society. And we can harness artificial intelligence to improve existing systems, predict and defend against hacks and realise a more equitable world.

Tackling the cybersecurity challenge is a matter of survival for society at large. Cyber attacks are rapidly increasing in sophistication and magnitude-and in their destructive potential. New threats emerge regularly, the last few years having seen a ransomware boom and distributed denial-of-service attacks leveraging the Internet of Things. For organisations, the use of cybersecurity risk management is essential in order to manage these threats. Yet current frameworks have drawbacks which can lead to the suboptimal allocation of cybersecurity resources. Cyber insurance has been touted as part of the solution - based on the idea that insurers can incentivize companies to improve their cybersecurity by offering premium discounts - but cyber insurance levels remain limited. This is because companies have difficulty determining which cyber insurance products to purchase, and insurance companies struggle to accurately assess cyber risk and thus develop cyber insurance products. To deal with these challenges, this volume presents new models for cybersecurity risk management, partly based on the use of cyber insurance. It contains: A set of mathematical models for cybersecurity risk management, including (i) a model to assist companies in determining their optimal budget allocation between security products and cyber insurance and (ii) a model to assist insurers in designing cyber insurance products. The models use adversarial risk analysis to account for the behavior of threat actors (as well as the behavior of companies and insurers). To inform these models, we draw on psychological and behavioural economics studies of decision-making by individuals regarding cybersecurity and cyber insurance. We also draw on organizational decision-making studies involving cybersecurity and cyber insurance. Its theoretical and methodological findings will appeal to researchers across a wide range of cybersecurity-related disciplines including risk and decision analysis, analytics, technology management, actuarial sciences, behavioural sciences, and economics. The practical findings will help cybersecurity professionals and insurers enhance cybersecurity and cyber insurance, thus benefiting society as a whole. This book grew out of a two-year European Union-funded project under Horizons 2020, called CYBECO (Supporting Cyber Insurance from a Behavioral Choice Perspective).
